In order to optimize the efficient use of cryopreserved stallion semen, recent research has focused on the minimum insemination dose of frozen-thawed spermatozoa required for maximum fertility rate. The results appear to be highly stallion-dependent. Factors such as the timing of AI with respect to ovulation, as well as the site of insemination within the mare's reproductive tract, also affect success in breeding with frozen-thawed semen. Since acceptable pregnancy rates can be achieved from insemination of mares with very low numbers of spermatozoa, increasing the number of insemination doses processed from a single ejaculate may prove more cost-effective to stallion owners.
